Dart’s Little M Sportsman Racing Block is designed to accept standard off the shelf stock parts. It features a standard cam location and size, and works with stock type oil pans. Unlike the Iron Eagle Blocks which require far more custom equipment, the Little M is a true racing block that utilizes standard hardware that fits standard Small Block Chevy Engines.

The Little M Sportsman differs from the Regular Little M blocks as a lower cost alternative featuring ductile (instead of steel) main caps with 4 bolts on center 3 caps, and 2 bolt on end caps. It also employs a rear external oil feed, crossover and restrictor provisions. This would be a perfect block for a street/strip performance engine without breaking the bank.

  • Uses standard small block parts, including cam, timing chain, oil pump, oil pan, oil filter, motor mounts, mechanical fuel pump, and clutch linkage.
  • Priority main oiling system feeds main bearings first.
  • Siamese cylinder bores with extra thick walls resist cracking and improve ring seal for more power (minimum .275” thick with 4.185” bore).
  • Scalloped water jacket walls improve flow around cylinders for better cooling.
  • Open lifter valley improves oil return to pan.
  • Enlarged lifter bosses accommodate offset and oversize lifters.
  • Blind head bolt holes don’t go through to water jacket.
  • Splayed outer bolts on middle main bearing caps.
  • Rear external oil feed, crossover and restrictor provision.
  • Parts kit sold separately.
